To all whom t may concern:

Be it known that l, WALTER HILL,a citizen of the United States,- residing at Mattoon,.in the county of Coles and State of Illinois, have invented new and' useful 'Improvements in Spring-i/Vheels, of'which the following is a specication.

lilhile the invention provides in effecta spring wheel of unique structure it -nevertheless embodies a yieldable tire which is adapted to be applied to a vehicle wheel of any design to take the place of the ordinary pneumatic tire to secure ease and comtures, 'details of construction and combination of parts, which hereinafter will -be more particularly set forth, illustrated in the accompanying drawing, and pointed out in the appended claim.

Referring to the drawing, forming a part of the specification, Figure l is a side view of a portion of'a vehicle Wheel embodying the `invention. Fig. 2 is a transverse section. Fig. 3 is a detail view of one of the "springs Corresponding and like parts are referred to in .the following description, and indicated in all the views of the drawing, by the same reference characters.

Since the invention dealsmore particu-I larly with the rim portionof the wheel the nature of the wheel per se is immaterial and .will not be referred to other than to state that it may be of any make embodying a rim A. l

The tire is yieldable and embodies a number of elements in its formation, said elements consisting of an; inner rim l, springs 2 and an outer rim 3u The rim 1 maybe ol`l any construction or outline in transverse section and is adapted to be bolted or otherwise secured to the rim of the vehicle wheel. The rim 3 is preferably constructed of spring metal and possesses a certain amount Specica'ti'on of Letters Patent. Application led December v2, y191.1. SerialNo. 663,579.`

Springs: 2 are approximately ofi l ranged transversely @flag wheel or the rims l 'and-,355

rhebuter `ends of the spningsg the inner side of thefrim-,Zgnngl -agreiseeure thereto. -Theinner fmtilieasprings '21 are bent t-o provide hooks lpwhieh enibracex are bolted or otherwise fastened. f

Corresponding and registering openings are formed in theends of the springs 2 and the edge portions of the rims l and 3 and bolts 5 pass through these openings and serve to secure the springs to the respective parts l and 3. The heads of the bolts co'nnecting the springs `to the rim 1 engage the inner side of said rim and the hooked ends 13 of the spring engage the outer edges of the heads of the bolts, thereby preventing any possible turning of the bolts after the parts have been assembled. rThe heads of the bolts connecting the outer ends of the Asprings 2 with the rim 3 are ribbed or otherwise roughened and are embedded or engaged by the tread 11, thereby preventing turning of said outer bolts. All the bolts 5 receive nuts 8 and are formed with transverse openings through which Cotter pins 7 pass, thereby preventing` accidental loss of the nuts. A. third rim Ll encircles the rim 3 and a filling 10 is interposedbetween the two rims 3 and 4t, said filling being of rubber, canvas or like material. The rim el and filling' 10 are secured to the rim 5% and outer ends of the springs 2 by means of the outer bolts 5. The tread 11 may be of rubber or other analogous material generally employed in the manufacture of soft tread tires. The tread 11 may be secured to the rim el in any manner. Bolts 9 pass through the tread 11 and through the parts '4, 10 and 53` and serve to secure all together. The heads of the bolts 9 project beyond the tread 1ll and sustain thewear and act to prevent slipping or skidding of the vehicle provided with the improved tire.'

It is pro osed to construct the tires in standard sizes and to connect the same to the rims of t-he Wheels by mean-z of bolts 12 which pass through the inner rim l and the rim A of the wheel. The springs 2 maybe of any strength and by reason of their formation and arrangement. are capable of withstanding severe strain and .in practice m1959521' if the outer edges of the rim 1 to which they-5:1

render the tire resilient toa degree to insure comfort and ease to the occupant oitlievehicle and to preventexcessive wear upon the lflriazhinery of mechanically propelled` ve- 1c es.v

Erorn the' foregoing description', t-aken'in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to'those skilled i-n the artto which the invention appertains, and while I have describedthe prlnciple of operation of the invention, vtogether with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device shownis merely illustrative, and that such changes may be madeY when desired as are within the scope of the claim appended hereto.

` Having thus described the invention what 20 is claimed as new, is

A tire of the character described comprising inner and outer spaced rims. springs of approximately U form arranged transversely of the rims in staggered relation and secured thereto, the inner ends of the springs having hooks which embrace the edges of the inner rim, and bolts connecting the inner `ends ofthe springs to the inner rim and having their heads engaged by the hooked .ends of the springs to prevent turning of the bolts.

In testimony whereof I aiix my signature in presence of two witnesses.
